We have reservations to be at WDW in the first week of October. Plan is to rope drop DHS for the 6am opening. Just now, I thought, that it might be dark and decided to look up sunrise times. 7:19 am. I have fished before sunrise a lot, but usually do not get in the boat until about half an hour before. Nautical twilight, which would be when you can still see stars and the horizon will start around 6:30 am. It is still going to be night when we enter the park and the land.
